WIRE CORSET-STAY.

Application filed February 24, 1913.

T 0 all whom it may concern Be it known that I, HARRY B. DowNnR, a citizen of the United States, residing at Bridgeport, county of F airfield, State of Connecticut, have invented an Improvement in Wire Corset-Stays, of which the following is a specification.

This invention has for its object to produce a corset stay formed from wire which will remain fiat under all the ordinary conditions of use, which while amply resilient will possess the desired degree of rigidity against forward and backward or sidewise fiexion, which will not buckle when flexed sidewise and which will provide a maximum of strength and durability with a minimum weight and a relatively small consumption of wire.

With these and other objects in view I have devised a wire corset stay comprising a relatively large central coiled strand having its coils extended to form eyes and intermediate portions, and relatively small side coiled strands likewise extended to form eyes and intermediate portions, alternate eyes of the side coiled strands engaging an eye or an intermediate portion of the central coiled strand and the intermediate eyes of the side coiled strand being disengaged from the central coiled strand.

In the accompanying drawing forming a part of this specification, Figures 1 and 2 are elevations illustrating the invention.

10 denotes the relatively large central coiled strand, and 11 and 12 the relatively small side coiled strands. The central and side coiled strands are shown as made from the same sizeof wire, although different sizes of wire may be used if preferred.

The method of manufacturing my novel stay is wholly immaterial so far as the present invention is concerned, it being deemed sutficient for the purposes of this specification to state that the coils of the side strands are wound in opposite directions and alternate coils of the side strands are threaded into the coils of the central strand. The forms illustrated difier only in that in Fig. 2 the relatively large central coil is wound upon an angular mandrel which gives to the coils relatively flat sides instead of the curved sides they naturally take when wound upon a round mandrel and as shown in Fig. 1. In both of the forms the coils of the relatively large central strand are so extended or spaced apart Specification of Letters Patent.

as to form in the finished stay eyes specifically indicated by 13 and intermediate portions specifically indicated by 14. The coils of the relatively small side strands are also so extended or spaced apart as to form in the finished stay eyes specifically indicated by 15 and intermediate portions specifically indicated by 16. Furthermore the coils of the central strand and the side strands are so spaced apart and proportioned relatively to each other that alternate eyes of side strand 11 engage successive eyes of central strand 10, leaving a free eye between each pair of engaged eyes, and alternate eyes of side strand 12 engage successive intermediate portions of central strand 10 leaving a free eye between each pair of engaged eyes.

Having engaged alternate coils of the side strands with the coils of the central strand, leaving a disengaged coil of each side strand between each pair of engaged coils, the strip, comprising the central coiled strand and the interlocked side coiled strands on opposite sides thereof, is passed between rolls, the effect of which is to fiat-ten the strip into shape for cutting into lengths and tipping. It will be noted that in the completed strip the flattened eyes of the central coiled strand and of the side coiled strands are slightly twisted, one edge of each engaged eye of a side strand lying under one side of the coil of the central strand with which it is engaged and over the other side of said coils. This slight twisting of the eyes provides an admirable resilient support for every part of the stay. The stay in other words is given the necessary rigidity that is required in use while at the same time there is ample resilience for both for ward and backward or edgewise fiexion and without danger of the stay buckling when flexed in any direction.

Having thus described my invention I claim:

1. A corset stay comprising a relatively large central coiled strand and relatively small side coiled strands, the coils of said strands being extended to form eyes and alternate eyes of the side strands engaging successive coils of the central strand and the coils of said strands being flattened into substantially the same plane.

2. A corset stay comprising a relatively large central coiled strand having its coils extended to form eyes and intermediate portions, and relatively small side coiled Patented Oct. 1a, 1913.

strands having their coils extended to form eyes and intermediate portions alternate eyes of one side strand engaging successive eyes of the central strand and alternate eyes of the other side strand engaging intermediate portions of the central strand, leaving alternate eyes of the side strands disengaged.

8. A corset stay comprising a central coiled strand and side coiled strands each composed of a single Wire, alternate coils of each side strand being interlocked With successive coils of the central strand and the coils of said side strands being flattened to substantially the same plane as the coils of 5 the central strand.

In testimony whereof I afiix my signature in presence of tWo Witnesses.
